rtlwifi: Remove logging statement that is no longer needed

commit aeb2d2a4 upstream.

In commit e9538cf4 ("rtlwifi: Fix error when accessing unmapped memory
in skb"), a printk was included to indicate that the condition had been
reached. There is now enough evidence from other users that the fix is
working. That logging statement can now be removed.
